SCALE FACTOR

                       

Description: This function allows the user to scale the selected lines or points with respect to any axis (global or local) using magnification factors in the X, Y, or Z (U, V, or W) directions.  Entering a scale factor greater than 1 will magnify the line, whereas a scale factor less than 1 will reduce the length of the line.

 

Usage:

 

1.   DSI prompts:

>       PICK LINES TO SCALE

>       SELECT LINES

 

 

•            Select DONE once the desired lines have been selected.

 

2.   DSI prompts:

>       CREATE LOCAL COORDINATES

>       PICK NODE/PT FOR ORIGIN

•      DSI asks for a coordinate system to scale the lines and prompts the user to create a local system.  A thorough explanation of how to create a local coordinate system is covered in Local Coordinate System, Section 2.16.

 

3.   Once the desired coordinate system is created, it will be displayed on the screen and the user will be prompted to accept or decline the system.  If the user accepts, then DSI prompts:

>      ENTER X, Y, Z SCALE FACTORS

•       The user selects the desired scale factors.

 

Example: The factors 1,-1,1 reflect the line size in the negative Y-direction (across the UV plane); the factors  0.5,0.5,0.5 reduce the lines by 0.5.
